Keto Chicken FajitasPin itFollow us 148.4k

Have you tried chicken fajitas? It's a great keto meal that takes no more than 30 minutes to prepare!

Fajitas are traditionally made with seared skirt steak that is cooked medium-rare and sliced into thin strips. When you use chicken instead of beef, it gets even easier because you don't need to worry about overcooking it. You simply slice the chicken breasts into thin strips and marinate them in spices, lime juice & olive oil. Then you pan-sear them and serve with charred vegetables.

I used my Keto Tortillas to wrap the fajitas. If you haven't tried them yet, these tortillas are a game changer for everyone following the ketogenic diet. They are perfect for wraps, easy to make and so versatile. In fact, I use the same dough for tacos, tortilla chips, breadsticks and even pizza crust.

You can make the tortillas plain or add spices such as garlic powder, paprika or cumin. It's one of the recipes I make on a regular basis and even my non keto friends love them! I wanted to show you how easy it is to make them so I created this quick video - I hope you like it :-)

  1. Start by marinating the chicken. Slice the chicken breasts into about 1/2-inch (1 cm) thin strips. Place the chicken into a bowl and add all the marinating spices: minced garlic, dried oregano, ground cumin, paprika, chipotle chile powder, salt, olive oil and lime (or lemon) juice.

  2. Mix until the chicken is covered from all sides, cover the bowl with a cling film and marinate for 30-60 minutes (or overnight in the fridge). When ready for cooking, remove from the fridge and discard the marinade (you need to remove any excess moisture before cooking the chicken strips in the pan).
    Start by cooking the vegetables. Peel and slice the onion and slice the peppers. Heat a large pan or casserole dish greased with 2 tablespoons of ghee over a medium-high heat. Once hot, add the sliced onion and peppers.

  3. Cook until crisp-tender and lightly charred for 5-8 minutes. Use tongs or spatula to toss the peppers every couple of minutes while cooking. When done, transfer the peppers into a bowl and set aside.
    Keep the heat on medium-high. Grease the pan with the remaining 2 tablespoons of ghee and add the chicken slices. Keto Chicken Fajitas
  4. Cook for 4-6 minutes until lightly browned, flipping half way through. Return the cooked peppers to the pan and heat through for just 30-60 seconds. Then, take off the heat. Keto Chicken Fajitas
  5. Serve with Keto Tortillas and any preferred toppings ... Keto Chicken Fajitas ... sliced avocado or Guacamole, chopped tomatoes or Salsa, shredded cheese, sour cream, lime wedges and cilantro. Keto Chicken Fajitas Enjoy! Keto Chicken Fajitas

I changed the way I ate in 2011, when I was diagnosed with Hashimoto’s, an autoimmune disease that affects the thyroid. I had no energy, and I found it more and more difficult to maintain a healthy weight.

That’s when I decided to quit sugar, grains, and processed foods, and to start following a whole-foods-based ketogenic approach to food.

Hi, how long do these keep for as it is just me who will be eating them? I could make less but some of the measurements would be a little off.

I'm sorry for the late response! They will keep for 4-5 days in the fridge. The tortillas will keep for up to about a week - or you can freeze them for up to 6 months.

You can also lower the carbs by just using lettuce leaf or other vegetable shell in place of the tortilla

Hi Martina,
So is one serve just one fajita? So 480cals and 13g total carbs per fajita? 😢

Yes it is one per serving but they are quite filling 😊 I only needed one and my partner had two. There are just about 6 g of net carbs per serving (here's why I count "net", especially when the carbs are from vegetables: Total Carbs or Net Carbs: What Really Counts?). There is less than 480 kcal because you won't eat all the olive oil (part is discarded) - I'll fix that and count it only partially. This, in fact will also have an impact on the carb count as part of the spices are discarded as well.

Make them every few weeks as love them. I hope you are making another cookbook as over halfway through this one.

Thank you so much! Yes, I've been working on a couple more cookbooks - this is the next one, it will be out next spring 😊
